Hi [~lkokhreidze] Could you try out the latest trunk for streams client (you do 
not need to upgrade broker versions) and see if it resolves the issue? I've 
pushed a couple of commits trying to fix this issue but unfortunately they are 
not in any released version yet.

Hi [~guozhang] 

Just fyi - we've experienced this error as well. Some of our Kafka streams jobs 
(with static membership) sometimes die whenever we restart one of the brokers. 
It affects broker version 2.3.1 and 2.4 as well.

We can reliably reproduce the issue in our "staging" environment so if some 
extra debug logs can be useful from clients/brokers would be happy to help.

guozhangwang commented on pull request #8269: KAFKA-9659: Add more log4j when 
updating static member mappings
URL: https://github.com/apache/kafka/pull/8269
 
 
   We could update the mappings when:
   
   1) known static member joins with empty member.id: we will generate a new 
member.id and put into the mapping, and if there's already an old member id it 
will be replaced.
   
   2) unknown static member joins with empty member.id: we will generation a 
new member.id and blindly put into the mapping.
   
   3) new leader loading __consumer_offsets and read consumer group generation 
messages.
   
   I suspect that there's a bug on broker side such that upon leader migration, 
the new leader did not load all the way up to the latest entry and hence in 3) 
above we mistakenly bootstrap the coordinator's cache with an old generation's 
mapping.

Guozhang Wang commented on KAFKA-9659:

My search in kibana has some good news and some bad news:

1) I can confirm that the blip on leaders cause the topic-partition 
__consumer_offsets-35, which stores this ksql consumer group, gets migrated 
from broker-2 to broker-11 around 00:55:22

March 5th 2020, 00:55:22.283controller-event-thread [Controller id=11 
epoch=157] Sending become-leader LeaderAndIsr request 
LeaderAndIsrPartitionState(topicName='__consumer_offsets', partitionIndex=35, 
controllerEpoch=157, leader=11, leaderEpoch=374, isr=[11, 9, 1], zkVersion=639, 
replicas=[2, 9, 1, 11], observers=[], addingReplicas=[2], 
removingReplicas=[11], isNew=false) to broker 11 for partition 
__consumer_offsets-35TRACE   kafka-11state.change.logger

And then later gets back to broker-2 about three seconds later:

March 5th 2020, 00:55:25.380controller-event-thread [Controller id=11 
epoch=157] Sending become-leader LeaderAndIsr request 
LeaderAndIsrPartitionState(topicName='__consumer_offsets', partitionIndex=35, 
controllerEpoch=157, leader=2, leaderEpoch=375, isr=[11, 9, 1, 2], 
zkVersion=641, replicas=[2, 9, 1], observers=[], addingReplicas=[], 
removingReplicas=[], isNew=false) to broker 2 for partition 
__consumer_offsets-35  TRACE   kafka-11state.change.logger

The tricky part is that while broker-11 is becoming the new leader, it is also 
included in the `removingReplicas` which sounds quite weird, I suspect that 
although the new group generation is written with ack=all and the broker-2 is 
elected as a clean leader, the previous election of broker-11 was wonky.

2) From all the fenced entries, e.g.:

March 5th 2020, 00:56:50.599data-plane-kafka-request-handler-3  given 
member.id ksql-0-3-70cb05ca-4687-4c1e-9c76-7a5a94da9961 is identified as a 
known static member ksql-0-3,but not matching the expected member.id 
ksql-0-3-db32cf5a-6d18-435b-bead-82fce848e239

I can find that the "new" member.id 
(ksql-0-3-70cb05ca-4687-4c1e-9c76-7a5a94da9961) was actually used in the past 
for committing for quite some time, for example:

Where as the "old" member.id cannot be found used anywhere besides the above 
ERROR logs, and without more logs I cannot conclude where on earth this 
member.id was introduced to the broker's cache at all.

Hi [~rohanpd] is the broker version the same as Streams (2.5.0-snapshot) here?
